BRAKE RIGGING.

Application filed July 24,

To all whom it may concern:

Be it known that I, SOREN HANssoN, a citizen oi? the United States, and resident o1"- Butler, in the county of Butler and State of Pennsylvania, have invented a new and useful Improvement in Brake Rigging; and I do hereby declare the following to be a full, clear, and exact description thereof.

- My invention relates to brake-rigging for railway cars, and one of its objects is to provide a novel and effective device in the nature of a clevis which, with minor differences in its shape, can be used as a plain clevis, as a brake-hanger or. as a truck and floating lever connection. In the latter case, two of the clevis devices are interlocked with each other and their ends are attached respectively to the floating lever and to the adjacent live lever.

Another object of my invention is to provide an improved method for making brakerigging attachments of the above-indicated character.

In the accompanying drawing, Fig. 1 is an elevational view of a truck and floating lever connection composed of clevis devices constructed in accordance with my invention; Fig. 2 is a longitudinal sectional view of the same construction, the section being taken substantially on the line 22, Fig. 1; Fig. 3 is a side elevational view of a clevis of a slightly different shape as compared with the devices of Figs. 1 and 2; Fig. 4: is a longitudinal sectional view of the clevis shown in Fig. 3, the section being taken substantially on the line 4-4, Fig. 3; Fig. 5 is a transverse sectional view taken substantially on the line 55, Fig. 3; Fig. 6 is a side elevational view of another form of device suitable for use as a brake-hanger; Fig. 7 is a sectional View of the device of Fig. 6, the section being taken substantially on the line 77, Fig. 6, and Fig. 8 is a transverse section taken substantially on the line 88, Fig. 7.

Each of the clevis devices herein shown is made from a single piece of flat stock in two principal operations of stamping and bending. In the first of these operations, a blank having straight sides and rounded ends is provided at its ends with flanged eyes and the sides of the blank are bent upward to form flanges which increase in height toward the center of the blank. The

1923. Serial No. 653,579.

blank is thereby tapered from its ends toward its center.

In the second or bending operation, the flanged blank is bent to bring the tapered ends of the blank parallel with the eyes opposite to each other and the flanged edges on the outside. The flanges formed on the edges of the blank may be formed of ,such depth that two'flanges engage each other at the center of the device as shown in Figs. 2, 4- and 7.

Referring first to Figs. 3, 4c and 5 of the drawing, the numeral 2 indicates the U- shaped body portion of a clevis havin openings 3 formed near the ends of its arms,

these openings being surrounded by flanges 4c. The sides of the body portion 2 are provided with flanges 5 increasing the width from the openings 6, where they merge intc the body portion to the points 7 where the flanges 5 are of maximum thickness and height. Between the points 7 the flanges 5 may be of uniform thickness and surround the closed ends of the clevis as shown in Fig. 4. These flange-s may engage each other on the line 8.

Figs. 1 and 2 of the drawing show a truck and floating lever connection composed of two interlocking clevis devices 10 which are somewhat longer in proportion to their width than the clevis shown in Figs 3 and 4, but which are otherwise similar and maybe constructed in the same manner.

The openings 11 in the ends of the members 10 are adapted for connection to the floating lever and the live lever of a set of brake-rigging and the loose connection between the members 10 permit the openings 11 to be set at different angles to engage these levers properly. If necessary, one or both of the members 10 may be twisted to bring the openings 11 into the proper angular position to suit the construction of any particular car.

Figs. 6 and 8 show a modified form of my device which may be used as a brake-hanger. Like the clevis shown in Figs. 3 to 5, this device has a U-shaped body portion 12 but in this case the end 13 of the body portion is made flat and has its inner surface curved as shown at 14 so that the hanger may be properly suspended from the usual brakehanger bearing. End openings 15 and side flanges 16 are formed on the body portion 12 in the manner described above in connection With Figs. 3 to 5, With the difference that these flanges are tapered only at the portions 17 adjacent to the ends of the body portion and have parallel spaced edges as shown at 18, Fig. 7, which ertendnearly to the bends Which join the arms of the hanger to the connecting portion 13. Adjacent to the connecting portion 13 the flanges are compressed together and engage each other on the line19 as shoWnin Fig. 7

In the claims appended hereto the term clevis is intended to include all of the several forms of my device herein shown and described, as Well as any other related forms Which fall Within the scope of my invention.

I claim as my invention:

1. A truck and floating lever connection for brake-rigging comprising two interconnected U-shaped members each having opposed openings formed near the ends of its arms.

closed ends of said members, and forming a rounded seat for the other U--shaped memher.

3. A brake rigging member comprising a U-shaped body member formed of a single piece of flat meta-land having opposed openings formed near its ends and also having flanges tapering from said openings toward the mid-portion of said U-shaped member, the edges of said flanges being bent out- Wardly into engagement with each other to form a bearing portion of reduced cross sectional area at said mid portion.

4. A. brake rigging member comprising a U-shaped body member formed of a single piece of flat metal and having opposed-openings near its ends and also having-outwardly turned flanges tapering from said openings toward the inid-portion oi: saidmember, the flanges being sodisposed that the member is of U-form in crosssection intermediate said openings, and the edges of the flanges having engagement With each other at the mid por tion of said body member to form a bearing portion of reduced cross sectional area.

In testimony whereof I, thesaid SOREN HANssoN, have hereunto set my hand.

SOREN HANSSON.
